When To Use "TOW HAUL"
1 — Tow/Haul Switch
2 — AUTO-6 (ERS) Switch
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the "TOW HAUL button once to select TOW
HAUL. In TOW HAUL mode, 4th to 5th gear upshifts are
STARTING AND OPERATING 289
delayed. Shifts into 5th and 6th gear are still allowed
under steady cruise conditions. Closed throttle down-
shifts (for improved engine braking) may occur during
steady braking maneuvers. Pressing the switch a second
time restores normal operation. Normal operation is
always the default at engine start-up.
The "TOW HAUL" light will illuminate in the instrument
cluster to indicate when the switch has been activated. If
the "TOW HAUL" modes are desired, the button must be
pressed each time the engine is started.
Electronic Range Select (ERS) Operation
The Auto–6 Electronic Range Select (ERS) shift control
allows you to move the switch down (-) or up (+) when
the shifter is in the D (Drive) position, allowing the
selection of the desired top gear. For example, if the
driver shifts the transmission into 3rd gear, the transmis-
sion will never shift above 3rd gear, but can shift down to
2nd or 1st gear, when needed.
